(a)

General performance standards for all industrial uses.

(1)

Purpose: The purpose of performance standards is to control industrial uses; to permit potential nuisances to be measured factually and objectively; to ensure that all industries will provide methods to protect the community from hazards and nuisances which can be prevented by processes of control and nuisance elimination; and to protect industries from arbitrary exclusion based solely on the nuisance production by any particular type of industry in the past.

(2)

Applicability:

a.

Any establishment of new principal or accessory industrial use or changed to the established industrial principal or accessory use on a site or in a building.

b.

If any existing use or building or other structure is extended, enlarged, moved, structurally altered or reconstructed, or any existing use of land is enlarged or moved, the performance standards for the district involved shall apply with respect to such extended, enlarged, moved or structurally altered or reconstructed building or other structure or portion thereof.

c.

All existing uses, buildings, or other structures shall comply with the performance standards herein set forth.

(3)

Performance standards:

a.

General provisions.

i.

All industrial uses shall conform to the standards of performance described within the provisions below and shall be so constructed, maintained, and operated so as not to be injurious or offensive to the adjacent premises by reason of the emission or creation of noise, vibration, smoke, dust, or other particulate matter, toxic, or noxious waste materials, odors, fire, and explosive hazard or glare.

ii.

All businesses, services, or manufacturing or processing of materials, goods, or products shall be conducted within completely enclosed buildings.

iii.

Storage may be permitted outdoors but shall be effectively screened by a wall, fence, or planting so that the materials shall not be visible from a public way or a residential area and shall be greater than 200 feet from the nearest residential district.

b.

Standards regulating nuisances.

i.

Noise. Any industrial use shall be operated to comply with the performance standards governing noise in Chapter 38, Article III, Noise Control, of the City Code.

ii.

Vibration. Any industrial use shall be so operated that ground vibration inherently and recurrently generated is not perceptible without instruments at any point on the property line of the property on which the use is located.

(a)

Vibration shall be measured at or beyond any adjacent lot line or residential district line as indicated in Table 67.2, Maximum Ground Transmitted Vibration, and such measurements shall not exceed the particle velocities so designated. The instrument used for these measurements shall be a three-component measuring system capable of simultaneous measurement of vibration in three mutually perpendicular directions.

(b)

The maximum vibration is given as particle velocity, which may be measured directly with suitable instrumentation or computed on the basis of displacement and frequency. When computed, the following formula shall be used:

Where: P.V. = 6.28 F × D

P.V. = Particle velocity, inches per second.

F = Vibration frequency, cycles per second.

D = Single amplitude displacement of the vibration, inches.

(c)

The maximum particle velocity shall be the vector sum of the three individual components recorded. Such particle velocity shall not exceed the values given in Table 67.2, Maximum Ground Transmitted Vibration.

Table 67.2: Maximum Ground Transmitted Vibration

(d)

If the site is greater than 200 feet from the nearest residential district, the particle velocity at the adjacent lot line may not exceed 0.20. Where vibration is produced as discrete impulses, and such impulses do not exceed a frequency of 100 per minute, then the values in Table 67.2 may be multiplied by 2.

iii.

Air pollutants: Including smoke, particulate matter, odor, and toxic matter.

(a)

Smoke. Every use shall be so operated as to prevent the emission of smoke as specified in "Rules of Department of Environmental Regulations: Air Pollution."

(b)

Particulate matter including dust. Every use shall be so operated as to prevent the emission into the air of dust or other solid matter as specified in "Rules of the Department of Environmental Regulation: Air Pollution."

(c)

Odor. Every use shall be so operated as to prevent the emission of objectionable or offensive odors in such concentration as to be readily perceptible at any point at or beyond the lot line of the property on which the use is located as specified in "Rules of the Department of Environmental Regulation: Air Pollution."

(d)

Toxic matter. The ambient air quality standards for guiding the release of airborne toxic materials across lot lines shall be in accordance with "Rules of the Department of Environmental Regulation: Air Pollution."

iv.

Fire and explosive hazards: All operations, activities, and uses shall be conducted so as to comply with the performance standards governing fire and explosion hazards prescribed by Indian River County Fire Rescue, and the State of Florida, and applicable technical codes.

v.

Glare: Any operation or activity producing glare shall be conducted so that direct light from the source shall not cause illumination in excess of 0.5 footcandles when measured in a residential district.
